In Japan loneliness is a big issue. I remember reading how people 70+ commit crimes JUST to go to prison, so they have somebody to care for them. (https://www.bbc.com/news/stories-47033704)
People can die from loneliness/depression. They just give up and then their health deteriorates. Yes it's not the loneliness that kills you, it is some organ(s) failing, but the root cause is loneliness/giving up.

That BBC article is, like many things they write about Japan, completely ignorant and click-baity. So you better look up other sources if you want to find reliable information.
